Tax Big Data Decodes the Chain Reaction of the AI Industry

After the 2026 World AI Conference concluded, a university-industry project from Nantong went viral, highlighting the city's innovation vitality in AI. Tax big data from the municipal tax bureau show that in the first half of this year, Nantong's fast-growing AI industry drove coordinated warming across the entire chain. Upstream nonferrous metal smelting sales revenue grew 29.6% cumulatively, computer and communications equipment manufacturing grew 46.8%, and amid computing-power and electricity coordination, optical fiber, lithium-ion battery and optical cable manufacturing grew 102.3%, 71.1% and 42% respectively. Langfeng New Materials Qidong, a national little-giant specialized enterprise long engaged in nanocrystalline soft magnetic materials, is accelerating its shift to automotive computing-power supporting markets; local tax authorities formed service teams and issued monthly reminders on filing and payment to guard against credit risks during expansion. Jiangdong Electronic Materials, rooted in upstream computing-power materials, has pushed its self-developed HVLP5 ultra-low-profile copper foil into the AI computing supply chain; the Rudong tax bureau pre-compiled policy checklists on R&D expense aggregation and high-tech enterprise incentives and delivered on-site one-firm-one-policy coaching. The company enjoyed over 58 million yuan in cumulative R&D super-deductions in three years, with AI computing-related orders up more than 50% year on year and R&D staff share rising from 11% to 22%. Jiangsu Shengyi Special Materials in Tongzhou leveraged self-developed ultra-low-loss high-frequency copper-clad laminates to seize the computing build-out, posting 690 million yuan in first-half revenue, up 64% year on year, with orders scheduled into 2027. The Hai'an tax bureau used tax big data screening to place Jiangsu Dinghong Electric Power on a key service list for the computing-power and electricity coordination chain, promptly adjusting invoice credit limits as orders and invoicing surged while coaching the firm on contract and cost accounting standards. At the workshop of Zhongtian Technology Submarine Cable, a global top-ten submarine cable maker, products widely support offshore wind bases and large intelligent computing centers. A municipal tax bureau official said tax authorities will closely track AI industry development, precisely implement tax and fee incentives, promote chain-based services and carry out regular tax compliance guidance.
